Can you type it out i can’t see the question
Answer:
Step-by-step explanation:
(13)2−(2x+7)=0
19x2−2x−7=0
9(19x2−2x−7)=9(0)
x2−18x−63=0
(x−21)(x+3)=0
Therefore, the value of x are
x - 21 = 0 and x + 3 = 0
x = 21 x = -3
Answer:
.1123 This is my guess, I'm not 100 percent sure though
Step-by-step explanation:
Add them all together, and then put 11 over it
11/98
Divide and this is .1122448979591837
If you round it ends up being
.1123
There are 1 right triangle, 1 rectangle and 1 trapezoid
- Solve for right triangle
1/2 x 5 x 8 = 20 cm
- Solve for rectangle
12 x 8 = 96 cm
- Solve for trapezoid
1/2 x 9 ( 5 + 10 ) = 67.5 cm
- The area of this is
20 + 96 + 67.5 = 183.5 cm
hope it useful for you :)
Answer: 0.3
Step-by-step explanation:
Because it took fewer than 7 boxes only 6 of the 20 simulated trials
P(fewer than 7 boxes) = 6/20 = 3/10 = 0.3
